DETAILS
Our most popular MIG wire, SuperArc® L-50®, premium copper coated wire, is an excellent choice for 50,000 psi (345 MPa) yield strength, carbon steel base materials.
Features
- Moderate levels of manganese and silicon for deoxidization of clean to light mill scale surfaces
- Superior feeding and arc stability
- Copper coated for long contact tip life
- Supports short-circuiting, globular, axial spray and pulsed spray transfer
